Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a positioning device for a seat pillar, and more particularly to a positioning device for positioning by an end stopper and a pair of side guides.

2. Description of the Related Art A conventional sheet piler conveys plate materials by a conveying means and stacks them on a support such as a pallet truck in an aligned state.To align the plate materials, an end stopper and a pair of side guides are provided. Therefore, a positioning device is often provided for positioning in the carrying direction and the width direction perpendicular to the carrying direction.

In this positioning device, conventionally, end stoppers are provided on the center line of the device, and both side guides are moved symmetrically with respect to the center line in the width direction to extend the position. .

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention Since this positioning device positions the plate material in the conveying direction by one end stopper on the center line of the device, the plate material easily tilts in the width direction about the end stopper, It is difficult to perform accurate positioning. In particular, when the shape of the plate material is such that it is difficult to prevent the inclination by the both side guides, it becomes more difficult. In order to avoid this, it is necessary to increase the size of the end stopper in the width direction so that the end stopper comes into contact with the plate material at two positions separated in the width direction. The problem is that access to the center line of the device is restricted and small plates cannot be piled.

Moreover, since the pair of side guides can only move symmetrically in the width direction, the plate material must be transported at a position symmetrical with respect to the center line of the positioning device. It cannot deal with offset conveyance that is conveyed out of alignment.

In view of the above circumstances, it is an object of the present invention to provide a positioning device having a wide range of pileable plate materials, capable of accurately positioning the plate materials, and capable of sufficiently handling offset conveyance. It was done.

Means for Solving the Problems And, the gist of the present invention is to provide one end stopper for each of a pair of side guides in a state of moving in the width direction together with the side guides, and for the width direction of each side guide. There is provided a side guide position adjusting device that can change the position of each side independently of each other, and an end stopper position adjusting device that can change the longitudinal positions of the side guides of the respective end stoppers independently of each other.

Action and Effect In the above positioning device, since the end stoppers are provided for the respective side guides, the plate material is positioned in the conveying direction at two positions separated in the width direction, and the tilting of the plate material is prevented. You can Moreover, since the end stoppers are provided so as to move together with the side guides, when the plate material is large, the distance between the two end stoppers is widened, and when the plate material is small, the distance between the side guides is obstructed by the end stoppers. It is possible to accurately position and pile large and small plate materials by narrowing the plate material without being caught, and the range of the plate material that can be piled is widened.

Also, since the two end stoppers can change the longitudinal position of each side guide independently of each other by the end stopper position adjusting device, even if the plate material has an asymmetrical shape with respect to the center line of the positioning device, it is accurate. It is possible to perform various positioning.

Further, the position of each side guide in the width direction can be independently changed by the side guide position adjusting device, so that the plate material to be offset-conveyed can be positioned.

As shown in FIG. 3, the side guides 54 and 56 are arranged such that the upper ends thereof are further apart from each other toward the upper end side, and both side guides 54 and 56 are
The plates are bent so that the space between them is wide, and even when the plate member 10 is released from the predetermined position in the width direction, the displacement can be corrected and positioned.

The movable frames 14 and 16 are also provided with end stoppers 68 and 70, one for each. As shown in FIG. 3 as an end stopper 70 on the movable frame 16 side, the stopper main body 72 is provided with a female screw portion 74, while the movable frame 16 is provided with a screw shaft 76 and a pair of guides along the upper surface thereof. 78 are arranged respectively,
The female screw portion 74 of the stopper body 72 is screwed onto the screw shaft 76, and the stopper body 72 itself is supported by the guide 78. As shown in FIG. 1, the screw shaft 76 is rotatably supported at both ends by screw bearings 80 fixed to the movable frame 16, and is rotated by a motor 82 with a reducer fixed to the movable frame 16. The rotation amount is detected by the rotation amount detector 83. Therefore, the end stopper 70 can be moved not only in the width direction together with the movable frame 16, but also in the longitudinal direction of the movable frame 16 along the guide 78 by the motor 82.

The end stopper 70 includes a stopper member 84.
As shown in FIG. 2, the stopper member 84 is bent so that its upper portion approaches the upstream side in the transport direction toward the upper end side. The stopper member 84 is connected to the arm 86 by a vertical shaft 85.
It is attached to the arm 86 by a fixing member 87 and is manually rotatable by 45 degrees in both directions from a neutral position facing the upstream side. The arm 86 is rotatably supported by the stopper body 72 by a horizontal shaft 88 and is urged to the upstream side by a spring member 89, while the arm stopper 90 fixed to the stopper body 72 limits the rotation to the downstream side. It is prescribed.

The end stopper 68 also has the same configuration including a stopper member 91 and the like. That is, the respective end stoppers 68, 70 are moved independently of each other in the width direction together with the side guides 54, 56 as the movable frames 14, 16 are moved in the width direction by driving the motors 34, 50, respectively. By driving 82, the movable frames 14 and 16 are moved independently of each other in the longitudinal direction.
In this embodiment, the motors 34 and 50, the screw shaft 26,
46, the movable frame support members 18, 44, the counter shafts 38, 48 and the like constitute a side guide position adjusting device, and the motors 82 and 92, the screw shaft 76, the guide 78 and the like constitute an end stopper position adjusting device. is there.

A front stopper 94 is attached to an intermediate portion of the support member guide 20 located on the upstream side. The front stopper 94 and each end stopper 6 are attached.
Positioning of the plate material 10 in the transport direction is performed by the numbers 8 and 70.

Further, as shown in FIG. 2, the end stoppers 68, 70
The support member 13 is provided between the front stopper 94 and the front stopper 94 so that the support member 13 can be moved up and down by an elevating device 98. The support member 13 is initially raised by the elevating device 98 and receives the plate material with its upper surface positioned between the upper surface and the lower surface of the side guides 54, 56, and is lowered with the increase of the plate material so that a fixed number of sheets are provided. The descent can be stopped in a state where the plate materials are stacked.

When the plate member 10 is positioned by the positioning device configured as described above, if the plate member 10 is large as indicated by the chain double-dashed line in FIG. 1, the screw shafts 26, 46 are driven by the motors 34, 50. Each of them is rotated to adjust the widthwise positions of the side guides 54 and 56 and the end stoppers 68 and 70 together with the movable frames 14 and 16 to widen their intervals. Since the plate material 10 is released from the belt conveyor 2 that is rotating, it falls while moving toward the downstream side due to inertia, and the two stopper members 8 separated in the width direction.
4, 91 is abutted and positioned while preventing inclination in the horizontal plane. The stopper members 84 and 91 are the plate material 10.
At the time of contact, the plate member 10 is rotated downstream together with the arm 86 against the urging force of the spring member 89, and as the elasticity of the spring member 89 is restored, the plate material 10 is returned to the original position while returning to the upstream side in the transport direction. The plate material 10 contacts the front stopper 94 at the upstream end and is positioned in the transport direction. Further, when the positional deviation of the plate material 10 in the width direction is large, the positional deviation is corrected by the guide portion having a wide upper end side spacing between the side guides 54 and 56, and the plate material 10 is fixed on both side guides 5.
Stacked between 4,56. A plurality of plate materials 10
Are similarly positioned and stacked, and then the side guides 54 and 56 are moved in the width direction with respect to the movable frames 14 and 16 by driving the cylinders 58 and 64, and the plate materials 10 stacked by that time Positions in the width direction are accurately aligned. After that, the supporting member 13 is lowered by the lifting device 98 by the thickness of the stacked plate members 10. Thereafter, the plate materials 10 are stacked while being similarly positioned, and the support member 13 is lowered to the lowest limit shown in FIG. 2, and then the stacked plate materials 10 are carried out by a transportation means such as a forklift.

When the plate material 10 has an asymmetric shape with respect to the center line of the positioning device as shown by the alternate long and short dash line in FIG. 1, the end stoppers 68 and 70 are independent from each other in the longitudinal direction as shown in the drawing. By moving and inclining each of the stopper members 84 and 91 along the downstream side of the plate member 10, accurate positioning can be performed on the asymmetric plate member 10.

The positioning is not limited to the case where the plate material is large as described above, and the positioning can be performed in the same manner for a plate material smaller than those. In this case, the side guides 54, 56 and the end stoppers 68, 70 are moved symmetrically with respect to the center line in the width direction to reduce the distance between them, and the end guides are moved according to the length of the plate material in the conveyance direction. The position may be adjusted so that the distance between the stoppers 68, 70 and the front stopper 94 is narrowed. The end stoppers 68 and 70 are side guides 54,
Since it moves in the width direction together with 56, it is possible to accurately position and pile not only a large plate member but also a small plate member.

The above is the case where the plate material is conveyed at a position symmetrical with respect to the center line of the positioning device. However, in the positioning device according to the present invention, even when the plate material is conveyed while being displaced from the center line of the positioning device. Can be dealt with.

For example, when two plate materials are conveyed in an offset manner, two positioning devices are arranged in series in the conveyance direction, and the positions of both side guides and end stoppers of one positioning device are changed independently of each other. Are conveyed at the central positions of the side guides and end stoppers, and the positions of the side guides and end stoppers of the other positioning device are adjusted to the conveyance positions of the other plate material. With this configuration, each plate member can be positioned by each positioning device. Conventionally, it was not possible to stack plates conveyed by offset transfer while positioning them with a piler.Therefore, a plate box for piles of the same shape as the plate materials was provided and the plates were positioned by loading it into the box. According to the positioning device of the present invention, it is possible to perform piles while positioning even the plate material that is offset-conveyed as described above. Therefore, it is not necessary to provide a pile box, and there is an advantage that productivity is improved. To be

The present invention is not limited to the above embodiments, and can be implemented in various modified and improved modes based on the knowledge of those skilled in the art.
